No spngy bone does not contain osteons. Compact bone does contain osteons.
Osteons are cylindrical structures found in the diaphysis (shaft) of long bones. They consist of concentric rings of bone tissue called lamellae, surrounding a central canal that houses blood vessels and nerves. Osteons are responsible for providing strength and support to the bone structure.
When old osteons are removed, concentric rings of lamellae are fragmented which then results in interstitial lamellaebetween the intact osteons.
The type of lamellae found between osteons is interstitial lamellae. These lamellae are remnants of old osteons that have been partially destroyed during bone remodeling.
Compact bone is dense and does not contain many spaces (unlike spongy bone). It has a concentric-ring structure. Compact bone consists of osteons which contains blood vessels and Volkmann's canals (which also hold blood vessels and nerves but run perpendicular to the osteons).

Compact bone tissue is adapted to support weight and withstand tension stress due to its dense structure and arrangement of osteons. These osteons are aligned in the direction of stress to provide strength and stability to the bone. This compact arrangement makes it ideal for weight-bearing and resisting tension.

Trabeculae are the small, rod-like structures that form the spongy bone, providing structural support while also allowing for lighter bone mass and space for bone marrow. Osteons, or Haversian systems, are the fundamental structural units of compact bone, consisting of concentric layers of mineralized matrix surrounding a central canal that contains blood vessels and nerves. While trabeculae are found in cancellous bone, osteons are characteristic of dense bone, highlighting the differences in their structure and function within the skeletal system.
